There are forty-nine gates of human understanding. The fiftieth gate is entirely beyond any living being.

It is so high that, looking down from there, all things are equally nothing. There is no good, no evil, nothing can be added or taken away, the righteous are dust, the wicked are dust, nothing is of consequence, all is but dust.

That is why Haman erected a gallows fifty cubits high upon which to hang Mordechai. To say: G‑d does not care. He is beyond all these things. There is no good or evil, it is all a fiction of the petty human mind.

Drunk with the joy of Purim, a Jew soars higher and yet higher until he reaches that gate. Upon entering, the Jew defiantly proclaims that the oppressed must be saved, the wicked overthrown, and light, joy, happiness, and peace must rule throughout the universe.

“As for this high place,” the Jew declares, “I am not impressed. It too was created for the purpose of our joy below!”

Yes, it is true that the higher you go, the less things matter. So why does anything at all exist?

Because an infinite, can-do-anything God chose that it should exist with joy, with love, and with goodness. He chose light over darkness, good over evil, liberty over oppression, the joy of Purim over the evil machinations of a powerful megalomaniac.

He chose, and that choice became the very fabric out of which this universe was formed, the theme of every story it tells, the meaning of every life, the message of every mitzvah we do.

Its secret exposed, the fiftieth gate itself is redeemed. It, too, has served its purpose.

So that, in the end, Haman was hanged on his own gallows, fifty cubits high.
